The Chemical Analysis of Argonne Premium Coal Samples
Edited by Curtis A. Palmer
1997
U.S. Geological Survey Bulletin 2144
This manual presents analytical data from currently recommended procedures as
well as procedures used in the 1980s by the geochemical laboratories of the U.S.
Geological Survey for the chemical characterization of coal and a comparison of the
results of these procedures for the Argonne Premium Coal samples.

For temperature conversions from degrees Celsius (°C) to degrees Fahrenheit (°F), use the following:
(1.8°C) + 32 = °F
Standard reference materials.-- The National Bureau of Standards (NBS) was renamed the National Institute of Standards and Technology (NIST) in 1988. In this report, standard reference materials from this agency are called NIST 1632a and so on, and the certificates of analysis of the reference materials are cited as National Bureau of Standards publications.
